Spray Drift data from Flat fan and air Induction nozzles in IRSTEA Wind tunnel

These data correspond to sedimented deposition in IRSTEA wind tunnel for different types of nozzles (Flat Fan Albuz AXI and Air induction Albuz CVI 02 - 2.5 bar) at different heights (40 - 60 - 80 cm) and different wind speeds (2-4-7.5 m/s)

Wind tunnel has a cross section of 2 x 3 x 9m (h x w x l) and sedimented droplets are collected on a distribution test bench (acc. ISO 5682) with grooves of 5cm width, 10 cm depth and 3m length.

Deposition is weighted after a certain volume (Max capacity of filling tubes 500ml) or a certain time (ex 30 min).

Each column gives the deposition value (expressed in relative flowrate) according to the settings inidicated on the first rows. The last row corresponds to the addition of deposition and provides the recovery rate on the distribution test bench.

Sprayed liquid is water.

4 nozzles spaced 50 cm are set on a boom at the defined height and pressure.

Input flowrate and pressure are controlled along the experiment.
Wind speed is controlled with a 2D US anemometer, air temperature and humidity are controlled with ad hoc sensors and with the help of heating/cooling system.

本数据集对应于不同类型喷嘴（平板扩散喷嘴Albuz AXI及空气诱导喷嘴Albuz CVI 02 - 2.5 bar）在多种高度（40cm - 60cm - 80cm）及风速（2m/s - 4m/s - 7.5m/s）条件下的沉积沉积物。风洞横截面尺寸为2 x 3 x 9米（高 x 宽 x 长），沉积物颗粒被收集于符合ISO 5682标准的分布测试台上，该测试台拥有5厘米宽、10厘米深、3米长的凹槽。沉积物在达到一定体积（填充管最大容量500毫升）或特定时间（例如30分钟）后进行称重。每一列提供了根据第一行所示设置得出的沉积值（以相对流量率表示）。最后一行对应于沉积物的累加，并在分布测试台上提供回收率。喷洒的液体为水。在预定高度和压力下，设置有4个间距为50厘米的喷嘴于吊杆上。实验过程中，输入流量和压力得到控制。风速通过二维风速计进行控制，空气温度和湿度则通过专用传感器及加热/冷却系统进行调节。
